    The NAC Transcription Factor ANAC089 Modulates Seed Vigor through the ABI5-VTC2 Module in Arabidopsis thaliana

    Yuan Tian, Lulu Zhi, Ping Li*, Xiangyang Hu*

    Phyton-International Journal of Experimental Botany, Vol.93, No.6, pp. 1101-1116, 2024, DOI:10.32604/phyton.2024.050220

    Abstract Seed viability is an essential feature for genetic resource conservation as well as sustainable crop production. Long-term storage induces seed viability deterioration or seed aging, accompanied by the accumulation of toxic reactive oxygen species (ROS) to suppress seed germination. Controlled deterioration treatment (CDT) is a general approach for mimicking seed aging. The transcription factor ANAC089 was previously reported to modulate seed primary germination. In this study, we evaluated the ability of ANAC089 to control seed viability during aging. Compared with that in the wild-type line, the mutation of ANAC089 significantly increased HO, thereby reducing seed viability after… More >

    Phyton-International Journal of Experimental Botany, Vol.92, No.5, pp. 1633-1647, 2023, DOI:10.32604/phyton.2023.027542

    Abstract Fatty Acyl-ACP thioesterase (FAT) is a key enzyme controlling oil biosynthesis in plant seeds. FATs can be divided into two subfamilies, FATA and FATB according to their amino acid sequences and substrate specificity. The Upland cotton genome contains 20 GhFAT genes, amongst which 6 genes were of the GhFATA subfamily and 14 of the GhFATB subfamily. The 20 GhFAT genes are unevenly distributed on 14 chromosomes. The GhFATA genes have 5 or 7 exons and the GhFATB genes have 6 or 7 exons. All GhFAT proteins have the conserved Acyl-ACP_TE domain and PLN02370 super family, the typical characteristics of… More >
